Ice at -12.1 °C and steam at 121 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 44.1 °C is present. Ignoring the container and the equilibrium vapor pressure of the liquid at 44.1 °C, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020 J/(kg C°). af Number i Initial state Units Steam - Ice Equilibrium Water
